Leading off our Monday Morning Quarterback blog today, in the wake of the Eagles' 15-7 loss to the New York Giants some 14 hours ago: What's going on with this offense, and can it be fixed with the current personnel?

After producing just three points in the last eight quarters, all against NFC East rivals, it's a question that must be answered soon, one way or another.

"We have to figure it out," wide receiver Jason Avant said. "There's something we're not doing. We have to figure it out, hop on the film."

The feeling here is that what the Eagles (3-5) see on video ultimately will have them looking in the mirror. Their schemes have been deciphered and their line has been neutralized by defenders who are exploiting every shortcoming.

Sure, it could have been and probably would have been a different story last week, had Nick Foles even completed 50 percent, extremely low by today's league standard, of his passes against the Dallas Cowboys in a 17-3 defeat.

And yes, it might have been different on Sunday against the Giants had rookie Matt Barkley not lost a fumble after driving the team to within 2 yards of a score late in the second quarter.

But the fact is that the book on the Eagles is out, and it advises opponents to play a style that G. Gordon Liddy might not endorse: to shoot for the chest, namely the little green area between the 2 and the 5 on ruuning back LeSean McCoy's jersey. Keep McCoy dead in your sights, get him down at all costs and force everyone else to beat you.

That includes the quarterback. Doesn't really matter which one.

So until the Eagles can find other ways to advance the ball consistently beyond handing to McCoy, they will continue to be shut down the way they were Sunday by the Giants and seven days earlier by the Cowboys

So it really all comes back to the quarterback, which leads us to Question 2: Just who is the quarterback anymore?

Is it Michael Vick, who won the job in a spirited preseason battle with Foles but had been sidelined since Oct. 6 with a hamstring pull? Vick hurried back on Sunday and instead made a case to be benched for good, before being allowed to leave (sort of the way Rommel was allowed by Hitler to off himself near the end of World War II).

Is it Foles, who was beyond bad against the Cowboys? Is it Barkley, who's still feeling his way and is not consistent enough yet to command a pro team?

It's a good bet that we'll go at least until Friday again before hearing any kind of announcement by coach Chip Kelly on the QB du jour.

And the beat goes on.

Finally, are the players starting to lose faith in the system or the odd decisions by Kelly at times to punt when he should go for it and vice versa, or in the latest head-scratcher, in which he ordered an onside kick in a one-possession game with more than four minutes to go?

No evidence of that yet.

Here's tight end Brent Celek: "We trust in the decisions that Chip makes. It's easy to sit back now and say `what if?' ... You can do that about anything. I'm not going to sit here and do that."

But if the Eagles keep losing the way they've been losing these last two weeks, eventually everything comes into question.

Kelly, being a rookie coach coming in from college, needs to avoid this at all costs, or he will be back in college ball before he knows it.
